将字符串转换为 JSON 时的未终止对象

Question

我正在使用Android Studio，我有一个字符串变量，叫做sResponse（下图）。根据调试器，它保存以下值：

 {
    "responseData": {
    "emotion":"",
    "lastinput":{actionResult={"value":{"label":"green","key":"1"},"result":"success","action":"displayClickableList"},
    "answer":"Sorry, I did not understand.",
    "link": {
    "href":"",
    "target":""
    },
    "extraData": {
    },
    "responseSession": {
    "id":"c4a5ef257851a991eb32c69132c9",
    "transaction":"4"
    },
    "responseDetails": "null",
    "responseStatus": "200",
    "applicationUrl": "http://noki-dev.cloud.com:90/moto-1/"
    }
    }

当我尝试以这种方式初始化 JSONObject 时：

jResponse=new JSONObject(sResponse);

。在我的 Logcat 中出现以下异常：

>>>>>>>>>Thread EXCEPTION1: Response with invalid JSON format: , FrontendActivity.java L:421 ***** *org.json.JSONException: Unterminated object at character 502 of : sResponse

我怀疑 URL 中的那些//正在造成麻烦。我不是转义 JSON 字符的专家。如何从上一个字符串中获取有效的 JSONObject？你能在我的方法中发现什么麻烦？

Answer 1

由于actionResult附近的符号=以及actionResult没有用双引号括起来并且您没有正确关闭 json 字符串而导致的问题。

将 JSON 字符串替换为：

{
    "responseData": {
    "emotion":"",
    "lastinput":{"actionResult":{"value":{"label":"green","key":"1"},"result":"success","action":"displayClickableList"},
    "answer":"Sorry, I did not understand.",
    "link": {
    "href":"",
    "target":""
    },
    "extraData": {
    },
    "responseSession": {
    "id":"c4a5ef257851a991eb32c69132c9",
    "transaction":"4"
    },
    "responseDetails": "null",
    "responseStatus": "200",
    "applicationUrl": "http://noki-dev.cloud.com:90/role-va-1/"
    }
    }
}

并在字符串末尾添加}。

您错过了响应末尾的最后一个收盘卷曲。只需在最后一行添加}即可。

更正的 json 响应

{
  "responseData": {
    "emotion": "",
    "lastinput": {
      actionResult: {
        "value": {
          "label": "green",
          "key": "1"
        },
        "result": "success",
        "action": "displayClickableList"
      },
      "answer": "Sorry, I did not understand.",
      "link": {
        "href": "",
        "target": ""
      },
      "extraData": {
      },
      "responseSession": {
        "id": "c4a5ef257851a991eb32c69132c9",
        "transaction": "4"
      },
      "responseDetails": "null",
      "responseStatus": "200",
      "applicationUrl": "http://noki-dev.cloud.com:90/moto-1/"
    }
  }
